1: we need to know the basic knowledge of physics, the weight formula quality m= P V2: magnet density is generally 7.45-7.6 kilogram per cubic decimeter. (specific density related with grades, N file is generally around 7.5, 7.5-7.6 high temperature resistant) volume is 3: long high width product of.4: because the magnet has the advantages of small volume, so the use of G as a unit
Know more information we can calculate a piece of square magnet weight.
If a square magnet for 10*6*5, N35 grade, the density estimate is 7.56 so that we can now calculate the magnet weight (10*6*5) *7.65/1000=2.295g
So the neodymium iron boron magnet weight is about 2.295g square
The following data are for reference only:
Several magnetic materials common density is: 1, sintered NdFeB, density of about 7.5 g / cm3 2, suppression of bonded NdFeB, density of about 6 g / cm3 3, sintered ferrite, density of about 4.9 grams / cubic centimeter 4, injection molding ferrite, density of about 3.8 grams / cubic centimeter. |
